OK, maybe time to qualify my statements... in my experience, having gone through the application process twice for this specific program, they do not ask for letters of recommendation. And further in my experience, any additional materials that are submitted with an application that are not requested get put in the trash. I'm sure that some maneuvering "behind the scenes" happens and may, in fact, make a difference; however, that's a dicey way to try to get into a school. Better to have a solid background and prerequisites and make sure that your application is properly completed (including, in this specific case, having written the appropriate essays) in a timely manner.
Also, I might add that the application process keeps changing for this program as the program itself evolves. The first time I applied, I was called in for an interview, because they were interviewing all qualified applicants. The second time I applied, they were only interviewing those applicants whose applications needed some clarification, or certain applicants at the discretion of the dirctor of the program. I did not interview, but I was accepted. I cannot speak directly to this year's application process, but I do know, from speaking to my instructors and the Second Career staff, they are doing some phone interviews.
